I have the Badger DBM as well and have had no feeding issues or problems of any kind, and Badger has been nothing short of stellar any time I have contacted them or needed anything. My question would be about your current stock set up, what are you running? If you are running the original stock and just don't want to reload as much you can look at far less expensive versions or mag extensions that will allow you 7 rounds or something vs. the standard 4. While I was waiting on parts for my build I bought one of these, and it served it's intended purpose until I got the DBM in my new stock. That cost was $21 vs. around $300 for a DBM system, not to mention $60 per additional 5 round AI mag and $70+ for 10 round mags. Depending on what model 700 you have and what stock it came with, it may not be worth getting a DBM system in. I started with an SPS tactical and the original stock was garbage. Putting a DBM on it would have caused more issues because of inletting that needs to be done for it to fit. That's not to say it hasn't been done, I just don't see the value in it.

Actually if you are interested in the mag extension for the time being I still have the one I used, it's for the short action.
